Just found some newly available climate layers useful for modeling, thought I'd share in case anyone hasn't seen this yet. This post topic might be expanded when our group gets together and discusses this resource.

Here's the link to the website:  CliMond 

The publication that goes into more detail is: Kriticos, D.J., Webber, B.L., Leriche, A., Ota, N., Macadam, I., Bathols, J. & Scott, J.K. (2012) CliMond: global high resolution historical and future scenario climate surfaces for bioclimatic modelling. Methods in Ecology and Evolution

CliMond is a set of free climate data products consisting of interpolated surfaces at 10' and 30' for recent historical climate and relevant future climate scenarios. The data is available as monthly climate data, 35 Bioclim variables, in CLIMEX format, and as the Köppen-Geiger climate classification scheme.
